Pin-by-pin modeling of fuel cycle and reactivity initiated accidents in LWR

  • 1. RRC 'Kurchatov Institute', Nuclear Safety Institute, Moscow (Russian Federation)

Description

This study deals with validation results for pin-by-pin methods to model fuel cycle and reactivity initiated accidents (RIAs) in LWR. Both methods are based on a heterogeneous pin-by-pin reactor model, realized in the BARS code. Validation results are presented for separate steps of WWER fuel cycle modeling. Features and advantages of a pin-by-pin approach for modeling of LWR RIA shown on the basis of calculations of control rod ejection accidents (REAs) in South Ukrainian NPP Unit 1 WWER-1000 and Three Mile Island Unit 1 (TMI-1) PWR at the end of cycles. Calculations were performed using the coupled RELAP-BARS code. Effects of pin-by-pin power and burnup distribution on estimation of the accident consequences are considered. (Authors)
